Title: Deflectable vehicle bumper
Inventor: SHEPARD ROY A
IPC: B60R19/02
Filed: 1989-11-15
Abstract: ABSTRACT OF THE DISCLOSURE            In a deflectable vehicle bumper comprising a central frame member attachable to the front of a vehicle, a pair of laterally extending wing members for protruding beyond the side of the vehicle, each said wing member is substantially coplanar with said the central frame member and attached thereto.  Each wing member comprises a rigid plate having an inner end portion overlapping and detachably secured to the central frame member, and each plate has a vertical line of weakness constituting a shear line outside the inner end portion, the shear line ensuring that the plate shears when a predetermined shear force is applied thereto.  A strip of resilient material is sandwiched between the overlapping plate and central frame member, the strip of resilient material being attached to the plate on each side of the shear line. The wing members are retained substantially in a laterally extended position during minor impacts, and the resilient sheet restores the wing members to the laterally extended position after shearing of the plate has occurred.

Abstract: ABSTRACT OF THE DISCLOSURE A mounting system for electric pumps used in automotive vehicles, especially those in which the pump is installed in the fuel tank.  To reduce pump and pump motor vibrations and noise, which may be objectionable to passengers, the pump is mounted within a jacket enclosure carried in the vehicle fuel tank.  A suspension for the pump within the jacket consists of identical mount rings of relatively soft flexible material which has internal and external relatively thin projections to contact the inner walls of the jacket on the outside of the ring and to contact the pump housing on the inside of the ring.  Radial continuations of the projections establish the axial location of the pump within the jackets.

Filed: 1990-06-26
Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is an everting balloon catheter in which the balloon has a waist at the desired eversion point to minimize the size of the distal tip of the catheter during insertion. Preferably, the distal  end of the outer body is bevelled and the waist is located just distal and radial to the tip of the outer body when the  inner  body  is  fully  extended  distal  to the outer body. Usually,  the  waist  is  formed by  heat  shrinking  the  balloon during manufacture, thus usually increasing balloon thickness at the waist.            Also, in the disclosed invention, the balloon is attached to the outer catheter body via heat fusion.  Generally, the outer body and the balloon are both formed of compositions having at least one component in common to promote heat fusion for attachment of the balloon.  Preferably that component is polyethylene.

Title: Safety means for powered machinery
Inventor: DUBOIS GERALD N III
IPC: B26D7/22
Filed: 1991-04-08
Abstract: ABSTRACT OF THE INVENTION    A safety means for powered machinery comprising a conventional wire mesh safety glove adapted for wearing by the machine operator.  The machine with which it is used has a grounded frame, an electrical motor, a control switch, with the electrical motor being connected to a source of electrical energy through the control switch.  The wire mesh glove of the operator is connected to the antenna of a radio transmitter worn by the operator.  The circuit breaking means includes a radio receiver means which remains closed when receiving an electromagnetic signal, i.e., a radio signal, but which will open when the anten-na of the radio transmitter is grounded to the frame through the wire mesh glove touching the frame which serves to interrupt the transmission of the signal.  This caused the electrical power to the motor to be interrupted.
